Siemens 6EP1961-3BA10 Switch Mode Power Supply

Siemens 6EP1961-3BA10 is a SITOP modular signaling module designed to accompany SITOP modular power supplies in the 6EP1XXX-3BA00 family. It provides three floating, normally‑open signaling contacts that report critical power‑supply status and enable remote control: DC OK (output voltage OK), Ready for operation OK, and Remote ON/OFF. These signals are intended for PLC input monitoring, interlocks, and safe remote control of the supply. The module uses signaling contacts separate from the main load circuit and is rated for DC signals up to 30 V and up to 0.1 A per contact. By integrating the 6EP1961-3BA10 with SITOP modular systems, engineers can implement remote shutdown in fault scenarios or feed status into diagnostic interfaces in automation panels, conveyors, packaging lines, or other industrial control applications where visibility of power status and remote control are required.
